John Lennon (1980)‘Thank You Girl’ was one of our efforts at writing a single that didn’t work. So it became a B-side or an album track.

「サンキュー・ガール」はシングルを書こうとしてうまくいかなかった曲のひとつだね。だからB面だかアルバムの中の1曲だかになったのさ。

Paul McCartney (1988)
We knew that if we wrote a song called, ‘Thank You Girl’ that alot of the girls who wrote us fan letters would take it as a genuine thank you. So alot of our songs were directly addressed to the fans.
